[0031] Secondly, the present invention is described in detail with reference to the schematic diagram.

[0032] Example 1

[0033] Reference Figure 1-4 , provides a new type of anti-vibration coupling, including:

[0034] Driven end portion 100;

[0035] The anti-vibration transmission part 200 includes a fixed frame assembly 201 and a universal transmission shaft 202. A gear assembly 203 is disposed inside the fixed frame assembly 201. The universal transmission shaft 202 drives the driven end part 100 to rotate by driving the gear assembly 203.

[0036] There are two shaft connection parts 300 , which are respectively installed at the axis of the driven end part 100 and the universal joint shaft 202 .

[0037] Furthermore, the driven end portion 100 includes an open housing 101 , and an inner ring of the open housing 101 is provided with an inner gear ring 102 .

[0038] Specifically, one of the two shaft-connecting parts 300 is connected to the rotating shaft of the wind turbine blades, and the other is connected to the high-speed shaft of the wind turbine gearbox. During daily operation, the wind turbine blades begin to rotate due to the influence of wind force, and their rotational force is transmitted to the gear assembly 203. After the gear assembly 203 rotates, it meshes with the inner gear ring 102, and then drives the opening cover 101 to rotate through the inner gear ring 102. After the opening cover 101 rotates, it will drive the high-speed shaft of the wind turbine gearbox to rotate, thereby completing the force transmission.

[0039] Furthermore, the fixing frame assembly 201 includes a disk 201a disposed inside the opening cover 101 and a base 201b disposed outside the opening cover 101, and the disk 201a and the base 201b are connected via a fixing rod 201c.

[0040] Specifically, the base 201b is fixed by bolts, and the disk 201a is arranged on the inner side of the opening cover 101 and is restricted by the fixing rod 201c, so that when the opening cover 101 rotates, the disk 201a will not rotate therewith.

[0041] Furthermore, three fixing rods 201c are provided, and the three fixing rods 201c are distributed in an isosceles triangle. The fixing rods 201c distributed in a triangle are more stable when fixed.

[0042] Furthermore, the gear assembly 203 includes two sets of linkage members 203a, both ends of the two sets of linkage members 203a are meshed with the inner gear ring 102, and a transmission gear 203b is provided between the two sets of linkage members 203a.

[0043] Specifically, the linkage 203a includes two parallel auxiliary connecting plates 203a-1 and two parallel main connecting plates 203a-2. The auxiliary connecting plates 203a-1 are rotationally connected to the main connecting plates 203a-2, and three auxiliary gears 203a-3 are rotationally connected between the two auxiliary connecting plates 203a-1, and a spur gear 203a-4 is rotationally connected between the two main connecting plates 203a-2.

[0044] Specifically, the three sub-gears 203a-3 and the two spur gears 203a-4 are meshed and transmitted in sequence, so that the spur gear 203a-4 at one end can drive the sub-gear 203a-3 at the other end to rotate, and the sub-gear 203a-3 meshes with the inner gear ring 102, thereby driving the opening cover 101 to rotate.

[0045] The end of the auxiliary connecting piece 203a-1 is rotatably connected to the disk 201a via a rotating shaft, and the rotating shaft is coaxial with the outermost auxiliary gear 203a-3, so that the outermost auxiliary connecting piece 203a-1 in the two sets of linkage parts 203a will rotate relatively along the rotating shaft as a fulcrum, and the outermost auxiliary gear 203a-1 is coaxial with the rotating shaft, so that when the auxiliary connecting piece 203a-1 rotates, it will affect the auxiliary gear 203a-3 and drive the inner ring gear 102.

[0046] Two sets of gear sets that can restrain each other from swinging are used as transmission. They not only have a wide range of XY direction compensation capabilities, but also obtain greater torque during the transmission process, ensuring continuous transmission of force and smoother operation.

[0047] The main connecting pieces 203a-2 in the two sets of gear assemblies 203 are rotatably connected through the rotating shaft 2, and the transmission gear 203b is sleeved and fixed on the outside of the rotating shaft 2, and the transmission gear 203b is respectively meshed with the spur gears 203a-4 in the two sets of gear assemblies 203. One end of the transmission gear 203b is installed on the universal transmission shaft 202. The rotation of the fan blades will drive the transmission gear 203b to rotate through the universal transmission shaft 202. After the transmission gear 203b rotates, it will drive the spur gears 203a-4 in the two sets of linkage parts 203a to rotate. The spur gear 203a-4 transmits the rotational force to the inner gear ring 102 through three sub-gears 203a-3, thereby driving the opening cover 101 to rotate.

[0048] Specifically, the universal transmission shaft 202 includes two flanges 202a and a roller 202b disposed between the two flanges 202a, and both ends of the roller 202b are connected to the two flanges 202a through universal joints;

[0049] The universal joint includes a transverse rotating block 202c symmetrically fixed on one side of the flange 202a, and longitudinal rotating blocks 202c are symmetrically fixed on both ends of the roller 202b. The transverse rotating block 202c and the longitudinal rotating block 202c are distributed in a "cross" shape, and the transverse rotating block 202c and the longitudinal rotating block 202c are rotatably connected via a cross block 202e. When the roller 202b is shaken, the roller 202b can be universally adjusted through the universal joint, effectively reducing the basic capabilities such as vibration and impact in the mechanical system.

[0050] This structure uses two sets of gear sets that can restrain each other from swinging as transmission. It not only has a wide range of XY direction compensation capabilities, but also obtains greater torque during the transmission process, ensuring continuous transmission of force, smoother operation, and effectively reducing basic capabilities such as vibration and impact in the mechanical system. It can ignore errors caused by generator alignment or vibration during operation, and improve the power factor of the equipment.

[0051] Example 2

[0052] Reference Figure 5 This embodiment is different from the first embodiment in that the shock-resistant transmission part 200 also includes a limiting component 204. There are two groups of limiting components 204, which are respectively arranged on the disk 201a to limit the up and down swinging strokes of the two groups of gear components 203.

[0053] Specifically, the limiting assembly 204 includes a rotating shaft 204 a and a limiting gear 204 b sleeved and fixed to the outside of the rotating shaft 204 a .

[0054] The two rotating shafts 204a are respectively rotatably connected to the disc 201a and correspond to the upper and lower sides of the two groups of linkage parts 203a. The limiting gear 204b is meshed with the inner ring 102. The inner ring 102 will drive the two limiting gears 204b to rotate. Normally, it can ensure that the inner ring 102 rotates more stably. When the fan blades vibrate, it will drive the two groups of linkage parts 203a to move relatively along the XY axis. During the swinging process, when the innermost sub-gear 203a-3 contacts the limiting gear 204b, it will be restricted to return to its position, thereby achieving the effect of swing restriction.

[0055] The rest of the structure is the same as that of Example 1.

[0056] Example 3

[0057] Reference Figure 6 This embodiment is different from the above embodiments in that the shaft connection part 300 includes a connecting rod 301, and a plug hole 302 is formed at one end of the connecting rod 301.

[0058] Specifically, a straight groove 303 is provided at one end of the connecting rod 301, and an arc groove 304 is provided on the outer side of the connecting rod 301, one end of the arc groove 304 is connected to the straight groove 303, and the arc groove 304 and the straight groove 303 divide one end of the connecting rod 301 into a C-shaped lower pressure ring 305, the lower pressure ring 305 and the straight groove 303 are fastened by screws, the fan blade shaft or the gear box high-speed shaft is inserted into the plug-in hole 302, and the tightening screw drives the lower pressure ring 305 to deform, so that it firmly clamps the fan blade shaft or the gear box high-speed shaft to achieve fixation, and has the function of easy disassembly and assembly.

[0059] The rest of the structure is the same as that of Example 2.
